Hi Guys,<div><br></div><div>I am looking to buy a 25 Watt output CyberData VoIP amplifier and to use 2 Bogen sp308a speakers with it for a 40, 000 squar feet area and 21 feet height. Is that enough? Is there calculator online I can use to determine the number of speakers needed? I guess these speakers go in chain so I am not sure if the full capacity of the speaker (30 watt) will be used.</div>
<div><br></div><div>I appreciate your advice.</div><div><br></div><div>Thanks,</div><div>Bruce</div>
